CC -!- FUNCTION: ATPase which is responsible for recognizing, binding,
CC unfolding and translocation of substrate proteins into the archaeal 20S
CC proteasome core particle. Is essential for opening the gate of the 20S
CC proteasome via an interaction with its C-terminus, thereby allowing
CC substrate entry and access to the site of proteolysis. Thus, the C-
CC termini of the proteasomal ATPase function like a 'key in a lock' to
CC induce gate opening and therefore regulate proteolysis. Unfolding
CC activity requires energy from ATP hydrolysis, whereas ATP binding alone
CC promotes ATPase-20S proteasome association which triggers gate opening,
CC and supports translocation of unfolded substrates. {ECO:0000256|HAMAP-
CC Rule:MF_00553}.
CC -!- SUBUNIT: Homohexamer. The hexameric complex has a two-ring architecture
CC resembling a top hat that caps the 20S proteasome core at one or both
CC ends. Upon ATP-binding, the C-terminus of PAN interacts with the alpha-
CC rings of the proteasome core by binding to the intersubunit pockets.
CC {ECO:0000256|HAMAP-Rule:MF_00553}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000256|HAMAP-Rule:MF_00553}.
CC -!- DOMAIN: Consists of three main regions, an N-terminal coiled-coil
CC domain that may assist in substrate recognition, an interdomain
CC involved in PAN hexamerization, and a C-terminal ATPase domain of the
CC AAA type. {ECO:0000256|HAMAP-Rule:MF_00553}.
CC -!- SIMILARITY: Belongs to the AAA ATPase family.
